A novel Zn(II) metal-organic framework [Zn-3(tib)(2)(L)(3)] (1) was synthesized with mixed ligands of 1,3,5-tris(1-imidazolyl)benzene (tib) and 4-carboxycinnamate (L2-), exhibiting interesting two-fold interpenetration, where triple-stranded homochiral left- (L-) and right- (R-) handed helical chains were constructed by linear rigid ligand L2- and metal ions. The complex was well characterized by single crystal and powder X-ray diffractions (PXRD), infrared spectroscopy (IR), elemental analysis (EA) and thermogravimetric analysis (TGA). As a result, the complex shows high thermal stability and strong photoluminescent emission in the solid state at room temperature. (C) 2012 Elsevier B.V. All rights reserved.
